media: iris: scale MMCX power domain on SM8250

Browse Source 
On SM8250 most of the video clocks are powered by the MMCX domain, while
the PLL is powered on by the MX domain. Extend the driver to support
scaling both power domains, while keeping compatibility with the
existing DTs, which define only the MX domain.
